USED OIL: In my experience, oil left over from deep-frying meat is OK to reuse to cook meat again, but not, for example, in deep-frying doughnuts.

SAVING OIL FROM DEEP FRYING:



After deep frying, cool oil completely. Strain oil into a large container with a good fitting lid. Refrigerate and keep oil in the refrigerator when not using.

Oil can be used as “cooked” oil 熟油 in seasoning meat in Chinese cooking, or in everyday cooking. It will darken in colour, but be good for 1-2 months refrigerated.

Use “used oil” up as soon as possible, and discards if it smells rancid or “off”, or smells like the food you have cooked it in.
